At block S2: the display device determines a page to be visited by the visitor. The page includes at least one controllable element, the controllable element refers to an element of which a color that can be controlled.

In one embodiment, the page to be visited i.e., a page that the visitor will browse. For example, if a URL is entered in a browser, a home page corresponding to the URL can be determined as the page to be visited. Then then content of the page is the screen information.

In one embodiment, the at least one controllable element includes one or more elements, such as at least one button, at least one menu, at least one line, a background, a text, and/or a combination thereof.

At block S3: the display device determines a current color scheme for the at least one controllable element of the page to be visited, according to the visitor information and the page to be visited, such that the color scheme matching the visitor is determined.

In one embodiment, the display device can determine the current color scheme for the at least one controllable element of the page to be visited, according to the visitor information and a page type of the page to be visited.

In one embodiment, the display device can determine different color schemes based on different visitors and different page types. Such that a one-to-one correspondence between the visitor information and the page to be visited is established.

Further, since different pages may have different layouts, different contents, and different page types, the color schemes of the at least one controllable element of different pages can be different.

In this way, through the one-to-one correspondence between the color scheme of the at least one controllable element of each page and the visitor information, a visitor who have visited a certain page can be determined according to the color scheme of the at least one controllable element of the certain page, and a traceability of the certain page can be realized.

At block S153: the display device determines a matching ratio according to the first total number and the second total number.

For example, if first total number equals 10, and the second total number equals 5, then the matching ratio equals 50%.

At block S154: the display device determines whether the matching ratio is greater than a second preset threshold.

The second preset threshold can be set according to an actual scene, for example, the second preset threshold can be set as 60%.

If the matching ratio is greater than the second preset threshold, block S155 is performed.

At block S155, the display device determines that the current color scheme matches the image color scheme.

If the matching ratio is less than or equal to the second preset threshold, block S156 is performed.

At block S156, the display device determines that the current color scheme does not match the image color scheme.

In this way, by setting the second preset threshold, the image can be compared with part of the visited page, such that the present disclosure can prevent the leaker from cropping the image or partially processing the image.

In an embodiment, before block S13, the method further includes:

Further, if there is no identification code in the image, the display device directly determines that the image does not match the visited page.

At block S164: the display device determines whether the identification code in the image matches the identification code in the visited page.

If the identification code in the image matches the identification code in the visited page, block S165 is performed.

At block S165, the display device determines that the visitor information corresponding to the current color scheme is the visitor of the image.

If the identification code in the image does not match the identification code in the visited page, block S166 is performed.

At block S166, the display device determines that the visitor information corresponding to the current color scheme is not the visitor of the image.

In this way, by adding the identification code to the visited page, and a combination of the identification code and the color scheme, the accuracy of matching can be improved.
